Btrfs To Go Production-Ready In Oracle Linux

Phoronix: Btrfs To Go Production-Ready In Oracle Linux

Btrfs, the quite promising next-generation Linux file-system that's been in-development for years by Chris Mason and others, is about to take on a big role within Oracle's Enterprise Linux distribution...

I'll switch from zfs-fuse when btrfs gets raid-5 support. They said they would do that once fsck was in place. So please implement it!

If at all possible, you should go with raid 10. That would give you speed advantages as well as increased robustness (as well as enabling data scrub recovery). Raid 10 has also been available for awhile now.
Raid 5 can be a death trap...

Right. I played around with zfs-fuse for a little bit. What a horrid mess. Unreliable, SLOOOOOOOOOW. Completely worthless.
BTW: MDRAID supports raid 5/6.... and is actually reliable. Nothing stopping you from running a btrfs over mdraid.

But can it recover from silent corruption errors as btrfs's RAID1(0) implementation could? I imagine, that if RAID5/6 is implemented within btrfs it can recompute the wrong block even if the hardware sees no fault. But with MDRAID the redundancy is transparent and cannot be used to recover, mesa thinks.

Michael, you've taken a quote out of context! When Avi said "BtrFS is that fast ALL the time," he was talking about mkfs.btrfs. No matter what size the filesystem is, mkfs will always be that quick. That has no connection to whether an XFS developer was shooting or not.

This file system has made great progress over the last couple years, im actually pretty excited about finally seeing it reach a stable enough status to go out with a distro and out to a wider audience. good stuff.
